BEINFOBOING DEVICE.

Specification of Letters Patent. Patented June 22, 1909.

Application filed April 27, 1909. Serial No. 492,578.

To all whom it may concern: I blades in alineme'nt, there being one wire 01 Be it known that we, WILLIAM F. KERLIN 3 rod for each row of blades, and each rod holdand EDWARD W. BOWEN, citizens of the ing all the blades of its row substantially in United States of 'America, and residents of I alinement.

In the modification shown in Fig. 3 the spectively, have invented certain new and construction is the same as that shown in useful Improvements in Reinforcing Devices, .1 Figs. 1 and 2 except that there are only four of :which the following 1s a specification.

This invention relates to certain new and useful improvements in reinforcement for plastic material such, f0r example, as the reinforcements shown in our application, Ser.

No. 433,744, filed May 19, 1908, and the object of the invention is to provide a novel reinforcement for a plastic body comprising a sheet of metal provided with blades extending in various directions, in order to insure the maximum reinforcement to a small quantity of-material, the said blades being reinforced by wires or rods which act to strengthen the same and make effective resistance to j j ployed.

any jar or pressure coming upon any part of the body when completed.

The invention may be embodied in different forms but two forms are shown in the draw 5 ings accompanying and forming part hereof. in which-'- Figure 1 is a cross section of a reinforced plastic post made in accordancewith my inr vention, the reinforcement being embedded therein. Fig. 2 is a perspective view of the reinforcement without the plastic material. Fig. 3 is a view similar to Fig. 2 but of a modified construction.

Referring now to the details of the drawings by numerals l desi nates a strip of metal of roper length and width which is slitted to orm two sets of blades on opposite sides of the body portion 1. These blades are formed by slitting the material on o posite sides of the body 1 at predeterminet intervals, and, as shown in Fig. 2, every third 5 blade 3 is kept in alinement with the body 1 while the intermediate blades 5 and 7 are bent on opposite sides of the body portion and at an angle thereto. There are thus in the form shown in Figs. 1 and 2 six sets of blades. two sets, on opposite sides, being in alinement with the body 1, and; the other four sets body 1 an body as clearly shown in said figures. free ends of the blades are preferably bent to form sleeves T which are emplpyed for the purpose of securing wires or rods 9 which ro ere for the purpose of holding all of the arranged on opposites'ides of the projecting at an anglefrom said The I sets of blades instead of six, the blades proi jecting from the body in alinement therewith 1 being omitted from form. In other words, this form is exactly the same as the form shown in Figs. 1 and 2 except that there i are no blades in'alinement with the body 9 From the foregoing and accompanying I drawings, it will be seen that we have provided a reinforcement for lastic bodies i which offers very effective resistance to any f jar or pressure coming upon the body and that a body of )lastic material reinforced with my device \viil offerthe greatest strength in proportion of the amount of metal em- The invention shown herein is broadlv protected in my aforesaid application filed May 19, 1908, 80.1. No. 433,744.

Z What we claim as our invention is:

1. A metallic reinforcement for plastic material comprising a flat body portion having a plurality of blades projecting from opposite edges thereof, said blades projecting at an angle to the body portion at opposite sides thereof, and wires or rods connecting the blades together. there being one wire or rod 1 for each set of blades and each wire or rod holding all the blades of its set in alinement.

2. A metallic reinforcement for plastic material comprising a flat body po'rtlon having several rows of blades projecting from oppo-' site edges thereof, one row on .each side remaining in alinement with the face of the body. and the other rows extending at an angle to the face of the body and disposed at opposite sides of the body, and wires or lmlS connecting the blades together.

3. A metallic reinforcement for plastic material comprising a flat body portion having its opposite edges slitted at predetermined distances throughout its length to form blades, said blades projecting at an angle to the body portion at opposite edges thereof and wires or rods connecting the said blades together. there being one wireor rod for each f set of blades and each wire or 'rod holding all the blades of its set in alinement. 5 4.
